I've loved how my Deco works generally. But recently, I want to say the past 2 months, I'm getting device offline notifications throughout the day, and it appears it's happening to most of the devices on my network. Some of the outages severe enough to require manually getting the devices back on the network. I have not been able to find any reason for this and the last new device I added to my network was in May of this year. I have since discontinued use of this device and removed it. I usually have 54 devices on the network, this model is capable of much more than that. I was told upwards of 150 when I bought it. I have noticed that quite a few of the devices that were configured for the IOT channel are no longer connecting to it, and in order to get them back on I have had to put them on the primary channel. My modem is Netgear CM 1000V2, I own it. I have rebooted several times, it doesn't seem to matter. I've checked for firmawre updates but there haven't been any since July 2024, which seems a long time. 

Does anyone have a suggestion for next steps?
